MEANS FOR MAKING COMPOSITE INSOLES.

Specification of Letters Patent.

PatentedjMarflfi, 1918.

Original application filed October 21, 1916, Serial No. 127,012; Patent No. 1,211,520, dated January 9, 1917.

Divided and this application filed January 6, 1917. Serial No. 140,916.

To all whom it may concern:

Be it known that I, FRANK ZALESKI, a subject of the Emperor of Germany, residing at Somerville, county of Middlesex, State of Massachusetts, have invented an Improvement in Means for Making Composite Insoles, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like arts. p This invention relates to means for making a composite insole of the type illustrated in U. S. Patents N 0. 1,206,927, dated December 5, 1916, and No. 1,211,520, dated January 9, 1917. The insole illustrated in said patents comprises an inner member having the edge thereof folded back upon the body thereof, and an outer member having the edge portion projecting beyond the periphery of the inner member and formed by folding back on itself the marginal portion of the outer member directly circumjacent the inner member, the peripheral edge of said outer member being free and forming a li The above-mentioned patents describe a procens of making an insole of this character which consists in placing the folded inner.

member upon the unfolded outer member, and while the inner and outer member are held in proper position relative to each other, folding the projecting marginal edge of the outer member back onto the body thereof and forming the peripheral edge of the outer member into a lip.

The device herein shown and which forms the subject of this invention is designed to accomplish this folding operation, and it comprises a support on which the unfolded outer member may be sustained, a die or forming member adapted to be POSltlOIlBd;

over the outer member, said die or formingmember having shape-giving edges that are spaced above the support, and folding mend-- bers adapted to act on the marginal edge of the under member and fold the latter over the shape-giving edges of the die member.

In order to give an understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claim. i I

Fig. 6 is a perspective view of the outer member before it is folded;

Fig. 7 1s a perspective sectional view showing the inner member placed in position on the outer member preparatory to folding the edge of the outer member.

Before describing my improved means for making an insole, I will refer briefly to the insole when completed. This comprises an outer member 1 and an inner member 2, each of which may be made of relativelythin sheet material, such, for instance, as leather, fabric or other suitable material. The inner member 2 has the edge thereof folded, and this edge will preferably be folded over onto the body of the insole, as shown at 3. The outer member extends beyond the inner member and the portion of the outer member immediately circumjacent the inner member is folded back on itself, as shown at', and the edge of the folded-back portion is then turned upwardly to present a lip 5. This folded portion 4 of the insole constitutes the feather ed e thereof, and the lip 5 together with the folded-over edge 3 of the inner member constitute the inseamreceiving rib for receiving the inseam stitches in the manufacture of a boot or shoe. The folded-over portion 4 of the outer member is preferably firmly secured to the body of the outer member so as to make a sufiiciently-stifi and solid feather edge to the insole.

The means herein illustrated are particularly designed for holding the inner'and outer members in proper relative position and then folding the marginal edge of the outer member so as to form the feather edge 4 and the lip 5 of the insole. The means I have herein illustrated for this purpose comprises a work support or table 9 on which the outer member 1 is adapted to be placed and which is of such dimensions that the portion 8 of the outer member which projects beyond the inner member and is fold-- ed over to form the feather edge and lip of the insole will project beyond the periphery of aid work support. Cooperating with the work support is a die or forming member 10 which is provided with templet elements 11 over which the portion 8 of the outer member is folded to form the feather edge and which gives the proper shape to said edge, and also folding elements 12 by which the portion 8 of the outsole member is folded over the templet elements 11. The die or forming member 10 will preferably have a portion at least of its under face constructed to rest on the upper member 2 of the insole when it is superposed on the lower member, all ,as shown in Fig. 1, and the templet or gage elements 11 are preferably situated above the lower face of the die member 10, as best seen in Fig. 1. In the illustrated embodiment of the invention, these templet or gage elements 11 are spaced above the lower face of the die member 10 a distance equal to the thickness of the inner member 2 of the insole. The gage or templet elements are also constructed for lateral movement relative to the die member 10 so that they can be expanded into operative posi tion or withdrawn from the fold, as will be presently described.

The die member 10 has lateral or trans verse dimensions substantially the same as that of the folded inner member 2, and the peripheral edge of the die member 10 is preferably rabbeted, as shown at 15, so that when the die member is brought against the inner member 2, as shown in Fig. 1, the infolded portion 3 of said inner member will occupy the rabbeted portion of the die member 10. Vith this construction when the die member is brought into operative position relative to the inner member 2 of the insole, the gage or templet elements 11 will rest on the infolded edge 3 of the inner member. The portion 16 of the die member 10 immediately above the templet elements 11 constitutes a lip-forming portion.

The device herein shown is constructed so as to admit of a relative vertical. movement between the folding elements 12 and the support 9, and the folding elements are arranged to have a transverse or lateral movement relative to the support 9.

In making the fold 4:, the outer member 1 is placed on the work support 9 with the edge 8 of the outer member projecting beyond the edge of the work support and overlying the folding elements 12. The inner member 2 with its edge folded is then placed in position on the under member 1 and the die or forming member 10 is brought into its operative position, as shown in Fig. 1, the gage or templet elements 11 being in their expanded position. The folding elements 12 are then moved upwardly into the dotted line position, Fig. '1, thus turning up the edge 8 around thegage elements 11, and 7 said folding elements are then moved inwardly over the gage or templet elements, as shown in Fig. 2, thereby folding the edge of the outermember 1 over the gage elements and up against the lip-forming portion 16 of the die member 10. The gage elements are then withdrawn inwardly, as shown in Fig. '3, and the folding elements 12 are moved downwardly to press the folded portion 4 of the outer member against the edge of the work support 9. This operation of the folding elements 12 not only forms the feather edge 1 of the insole, but also turns up the lip 5, thus giving the final and desired shape to the insole.

After the insole is thus completed, the folding elements 12 are returned to the position shown in Fig. 1 and the die member 10 may be separated from the work support 9 to permit the completed insole to be removed.

It is desirable that the inner and outer members should be firmly secured together and also that the two plies of the foldedover portion 4 of the outer member should be firmly secured together to make a solid feather edge. One way of doing this is by the means illustrated in said above-mentioned Patent No. 1,211,520, wherein the outer member is provided with an adhesive coating 6 so that when the inner and outer members are placed in proper relative position and the folding operation is accomplished, the parts will be firmly secured together as desired. The adhesive material 6 may have the characteristic that it is not sticky or tacky under normal temperatures, but will become so when subjected to heat, and if adhesive of this form is used, the work support 9 may be heated in some suitable way so that the heat thereof will soften the adhesive 6 during the folding operation, thus causing the parts to be secured together as desired. The advantage of using this adhesive which is not sticky or tacky at normal temperature is that the gage elements 11 are not liable to stick or adhere to the coated surface of the outer member 1 during the folding operation.

It will be understood that the movable parts of the device may receive their motion by any suitable means.

This application is a division of application for United States Letters Patent Se. No. 127,012, filed October 21, 1916, and which has matured into the abovermentioned United States Patent No. 1,211,520.

While I have illustrated herein a selected embodiment of my invention, I do not wish to be limited to the constructional features shown.

I claim:

Means for making insoles comprising a support for the sheet material of Which-the insole is made and which is of less transverse dimension than said sheet so that when the sheet is placed thereon the marginal portions of the sheet extend beyond the support, a die or forming member positioned over the material and provided with a collapsible templet having shape-giving edges which are spaced above the support, and folding members surrounding the support and normally having their upper edges being operative to infold said marginal por- 15 tion over the templet members.

In testimony whereof, I have signed my name to this specification.

FRANK ZALESKI.
